Difference between Rat and Hamster

Key Difference: A rat is a medium-sized to large rodents, with a pointed muzzle, long slender and hairless tail, and dexterous forepaws. A hamster is a rodent that belongs to the Cricetidae family of the Rodentia order. They are small in stature, are stout-bodied and have short, stocky legs with wide feet.

Rats and hamsters are two of the most popular pets that are available for people that prefer to take care of small pets, rather than dogs or cats that require more responsibility. At one glance, it can be really easy to become confused between rats and hamsters as they are both small creatures and have a similar appearance. Rats and hamsters are not the same, but can be considered as cousins (maybe once or twice removed). Rats and hamsters belong the same superfamily and different between families and subfamilies.

A rat is a medium-sized to large rodents, generally described as pigeon-sized. They are usually distinguished from mice by their size, but are also known to have a pointed muzzle, long slender and hairless tail, and dexterous forepaws. Like mice, these rodents are also found throughout the world, in varying environments and are nocturnal.

Rats are considered as deadly pests, especially because they often carry deadly diseases. They have been known to have a big part in spreading the Bubonic plague throughout Europe. They are also known to damage and eat crops, and cause structural damage. In some parts of India, every fifty years, armies of bamboo rats descend upon rural areas and devour everything in their path. Also, it is believed that there are up to 4 times more rats in New York City than there are people.

There are many species of rats, including, Philippine forest rat, Polynesian rat, Himalayan field rat, Sunburned rat, Rice-field rat, Summit rat, Nonsense rat, Palm rat, little soft-furred rat, Malayan field rat, Spiny rat, Australian swamp rat, long-haired rat, etc. However, of these the most commonly found and popularly known is the Brown rat or Norway rat and the black rat.

A hamster is a rodent that belongs to the Cricetidae family of the Rodentia order. They are small in stature, are stout-bodied and have short, stocky legs with wide feet. Hamsters have approximately six to seven genera, with over 25 known species. Hamsters have a small tail, that is generally shorter than their body and the amount of fur on their tail differs depending on their species. Although widely believed as nocturnal, hamsters are actually crepuscular creatures, meaning they are active during twilight, dawn or dusk. They prefer to sleep during daylight. However, many pet hamsters may change their daily sleeping habits depending on what they prefer. These rodents are crepuscular to keep themselves away from predators by burrowing holes in the ground during the day.

Hamsters are omnivores that prefer a diet of dried food, seeds, berries, nuts, fresh fruits and vegetables. They may also occasionally eat burrowing insects. Similar to other burrowing rodents, hamsters have extra skin in their cheeks that allows them to carry and store food for transport. They have solitary natures and prefer to stay along. They may even become aggressive if they are kept with other hamsters or animals. Hamsters are timid in nature and scare easily, which is one of the reasons why a mother often eats her young if she suspects danger.

Hamsters become fertile at the age of 4-5 weeks, which can change depending on their species. The female’s reproductive life lasts about 18 months and the females are in estrus about every four days. Following mating, the male should be separated from the female or she will attack and can even kill the male. The males should also not be present during birth of the children; they can attack and kill the females or the young. Hamster pups are born in a litter of 6-7 pups per litter. Hamsters are born blind and hairless and wean at the age of 3-4 weeks.

Hamsters make popular pets as they require less maintenance and prefer to stay in solitary conditions. They also require less time and energy and only require small amounts of exercise. Hence, they are the most preferred choice, when trying to teach children of responsibility of pets. Hamsters are also popularly used as laboratory rats because they are easily bred.

Thank you for detailed information feedback

"Rats are considered as deadly pests"? Was this article written on the middle ages. Clueless.. Plague was started by fleas. Not rats.

And those fleas were carried by rats
